I opened itunes and it asked to update my ipod touch to 1.1.4. My ipod touch (16 gig) came with the 1.1.3 update and it is NOT jailbreak. It's completely clean from any of that. When I was installing the update from itunes, it started to backing up my ipod files then went to install. It ended with an error 1604 or something along that line and my ipod stopped working. My ipod can be turned on and off, but it will have the ipod charger with an arrow to the itunes icon. And when i leave it alone, the ipod ends up turning itself off! I try to connect it to itunes, and my itunes wont detect it anymore. Any help would be highly appreciated. this is my first mac product and I was disappointed already by the itunes program and now worried about my ipod. I bought it directly from apple.com as well. i tried searching on their support, and there was no help. the closest thing they had was the 1.1.3 help.
